Hello, My dad has a train set and he is selling it all and its my task to categorize and price every part of it. Most of it is Lionel and I have a price guide for Lionel but a few are from my grandfathers and are what seems to be O guage American Flyers, im guessing from the 1930s or 1940s based on his age. I can't seem to find it online anywhere but if anyone can help with a price would be appreciated. Here is the info: -American Flyer Train (exterior has #3113) -Appears Tin Made and appears to be an electric street car as his is powered but doesn't look like a locomotive. - Tag on bottom just says "Made by American Flyer Mfg Co. Chicago, Ill Patented" - One part has imprinted PAT'D 1-10, 1922 -Condition: Very dusty, Paint appears good, no rust, not sure if it works as we never had a working O guage in our house. Thanks!!
